Originally shot in 3-D and newly remastered and restored, Alfred Hitchcock's screen version of Frederick Knott's stage hit is a tasty blend of elegance and suspense casting Grace Kelly, Ray Milland and Robert Cummings as the points of a romantic triangle.

She loves Cummings; her husband Milland plots her murder. But when he dials a Mayfair exchange to set the plot in motion, his right number gets the wrong answer - and gleaming scissors become a deadly weapon.

Dial 'M' for the Master of Suspense at his most stylish. Presented in 3-D, as originally intended!
